慎用prevent ，他会阻止一些默认时间，比如在移动端使用了之后，移动端的默认事件都有：

1.  长按会进行复制

2. 下拉滚动等

这些都不起作用了。如果不想用复制，可以给根元素设置user-select:none

不建议直接使用prevent，请在真机上测试使用

Prevent Errors

Giles Colborne

ERROR MESSAGES are the most critical interactions between the user and the rest of the system. They happen when communication between the user and the system is near the breaking point.
It is easy to think of an error as being caused by a wrong input from the user. But people make mistakes in predictable, systematic ways. So it is possible to “debug” the communication between the user and the rest of the system just as you would between other system components.
For instance, say you want the user to enter a date within an allowed range. Rather than letting the user enter any date, it is better to offer a device such as a list or calendar showing only the allowed dates. This eliminates any chance of the user entering a date outside of the range.
Formatting errors are another common problem. For instance, if a user is pre- sented with a Date text field and enters an unambiguous date such as “July 29, 2012,” it is unreasonable to reject it simply because it is not in a preferred format (such as “DD/MM/YYYY”). It is worse still to reject “29 / 07 / 2012” because it contains extra spaces—this kind of problem is particularly hard for users to understand, as the date appears to be in the desired format.
This error occurs because it is easier to reject the date than parse the three or four most common date formats. These kinds of petty errors lead to user frus- tration, which in turn lead to additional errors as the user loses concentration. Instead, respect users’ preference to enter information, not data.
Another way of avoiding formatting errors is to offer cues—for instance, with a label within the field showing the desired format (“DD/MM/YYYY”). Another cue might be to divide the field into three text boxes of two, two, and four characters.

￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼Cues are different from instructions: cues tend to be hints; instructions are verbose. Cues occur at the point of interaction; instructions appear before the point of interaction. Cues provide context; instructions dictate use.
In general, instructions are ineffective at preventing error. Users tend to assume that interfaces will work in line with their past experience (“Surely everyone knows what ‘July 29, 2012’ means?”). So instructions go unread. Cues nudge users away from errors.
Another way of avoiding errors is to offer defaults. For instance, users typically enter values that correspond to today, tomorrow, my birthday, my deadline, or the date I entered last time I used this form. Depending on context, one of these is likely to be a good choice as a smart default.
Whatever the cause, systems should be tolerant of errors. You can facilitate this by providing multiple levels of undo to all actions—and, in particular, actions that have the potential to destroy or amend users’ data.
Logging and analyzing undo actions can also highlight where the interface is drawing users into unconscious errors, such as persistently clicking on the “wrong” button. These errors are often caused by misleading cues or interac- tion sequences that you can redesign to prevent further error.
Whichever approach you take, most errors are systematic—the result of mis- understandings between the user and the software. Understanding how users think, interpret information, make decisions, and input data will help you debug the interactions between your software and your users.

git分支切换 Untracked Files Prevent Checkout
新起的项目在切换master分支到工作分支时，出现下图的问题：
Untracked Files Prevent Checkout
Move or commit them before checkout

网上的解决办法：
大多都是执行git  clean  -f  ，将所有untracked file 一次性删除。
本人发现执行该命令后会把项目的文件删掉，难以达到预期效果。
本人解决办法：

进入工程所在目录
右键打开Git Bash Here
执行git checkout -f RE20191205-BETA-298 （RE20191205-BETA-298是我想切换的分支）
这样再回到IDEA会发现分支已经切换过去了。
